Description

Technical Field

[0001] The utility model relates to the field of cutting jig devices, in particular to an adjustable pneumatic scissors gate cutting jig. Background Art

[0002] When the injection mold is injected from the side, the product produced by injection molding is attached to the gate, and the gate needs to be manually trimmed and removed later. This is labor-intensive, time-consuming, and has low production efficiency.

[0003] Instead of the traditional method of removing the gate by manual trimming, an adjustable pneumatic scissors gate cutting fixture is used to solve the problem. The principle is: the pneumatic scissors gate cutting fixture is supported on the ground with a bracket, and the distance between the pneumatic scissors is adjusted according to the distance between the mold products. After the injection molding is completed, the robot takes the product with the sprue, and then moves it above the pneumatic scissors, so that the blade of the scissors is aligned with the connection between the product and the sprue. Then start the scissors to cut the sprue and separate the product. The robot then sends the separated product and sprue to the designated place. The scissor position of this fixture can be adjusted at will according to the position of the mold product, and is suitable for multiple sets of molds. It saves costs, reduces labor, and improves production efficiency. Utility Model Content
